I think this thread will need for the op to maintain a curated list of some kind at the top. Not many will see the middle 95% of a thread of random videos. Good idea. I will collect an ordered list of channels at the top post. But people are free to post new videos and channel announcements at the …

I do believe that the chipset can do this faster! Probably had wider or faster access to the memory than the SX with its meager 16 bits...

I think EMM386 acquires memory via HIMEM.SYS in the XMS area, but actual EMS emulation is done via the MMU and not quite that slow. But my memory might be a bit fuzzy.

Hi, So my channels are root42 and root42plus . I solder smaller projects that I find on the web, document my retro PC builds and review my favorite games of my childhood. On the second channel I put up bonus content, raw capture footage, without me annoyingly talking over music and stuff. Hoppe you …

Hey everyone, Since there are quite a bunch of Vogons that produce a number of instructional, educational or entertaining videos, I think it might deserve a thread of its own, where you can post a link to your newest video, playlist or channel. Instead of cluttering other subforums or having it …

No need for a specific EMS driver. EMM386 will work just fine on a 386SX, since it emulates EMS via v8086 mode, which is available on every 386.

Hardware. For DOS you need a real MIDI hardware device connected to your soundcard's MIDI output. E.g. some Roland SC-55, SC-88 or similar. Or one of dreamblaster's new devices: https://www.serdashop.com/Webwinkel-Product-198933047/Dreamblaster-S2-General-MIDI-Module-Bundle.html This is not so much …

If the CMOS clear jumper is not set, you can trace the battery using a multimeter. Try to see where the 3V from the coin cell goes on the disconnected, powered down motherboard.

I like the Midi Blaster: looks like a bunch of ROMs with Creative Stickers on them. Besides the 74 series ICs the other ones are probably Waveblaster ICs? I guess the device is from the early SoundBlaster 16 era? I can only offer a screengrab from my SC55 video: 44F4B7E5-684D-4952-9D48-181A37CF04DB. …

The vi fans will beg to differ. 😀 I learned on Turbo C 2.0 and then switched to djgpp and emacs as well as gdb. I even used a Hercules card for gdb so I could debug VGA mode X programs.

I wouldn't expect any significant difference either, apart from the parameters that fitzpatr mentioned. But feel free to do so e benchmarking yourself! Could be interesting.

I think I will try out OS/2 1.3 at some point on my 286. never used such an old version. Really wonderinf what it can do. 😀 I used Warp 3 quite some time as a mainstay operating system in the mid 90s. It was really, really nice.

Very nice. With Miles Sound System being documented, this will be an order of magnitude easier than reverse engineering an iMuse driver, if that is possible at all...
